- 0:00Right now, I'm in little right now sitting just that's i are
- 0:02live in your window is this what's basicly a fifteen tonn
- 0:07pressure is biological water tower.
- 0:10We're cataly just call it tree. And you know miss the time, it's
- 0:14just this picture asc provider of shate right just the
- 0:18beautiful ps of senory that frame your property, you're
- 0:20think about. It's just back out and till
- 0:23weather turns. Xacly but one a massive Adam
- 0:26Storm hits and the Sky bruses this uguy purple.
- 0:30The illusion of that peaceful static garden just completely
- 0:35shatters instantly you watch this massive organizum lash back
- 0:39infort in the gail. We think at these angles that on
- 0:41as leed to fy gravity. It's terrifine when you actually
- 0:44patient and do what's happening mechanicly get.
- 0:46Realias and the sudden Realisation Kind of washes of
- 0:49you rate, the only think people that clossilate from crashing
- 0:52strate to your you know expensive glass conservatory or
- 0:55words, you're bedram roof is this micro scotic layer of ruts
- 0:59and a really. Radual highly Strange balance of
- 1:01Structural physics. Yeah, that psychological shift
- 1:04is profound. I'm you going from a mirring
- 1:07nature to sevily reckignising a highly liefal that right and
- 1:10your back, yard, structually and architectually and a ture tree
- 1:15is a hydre static marvel shore, but it is also an an tirly
- 1:19unpredicible for's of nature ray, we're taking about origin
- 1:23is harboring like. Tin the fifteen tons of mass of
- 1:26biomass and it's all suspended high up in the.
- 1:29Air, which is just i'm in the mass alone is stagring when we
- 1:32say fifteen tons. We're talk about the equipment
- 1:34of a fully loted city bus just standing verticlee in your
- 1:37backyard. Is and the density of that mass
- 1:40is what people all we's all we's Miss calculate it's not just dry
- 1:44timber. It's miss the water.
- 1:45Right it is a highly active hydrolic system.
- 1:48The what is compleedy satrate it's activeling hundred of
- 1:52leaers of water aga. The kind of be.
- 1:55Ok, that's an pact is because when you take a fully saterated
- 1:58fifteen ton by logical structure and introdus well katastropic
- 2:02instability and a dancely populated area, which is the
- 2:06fokal point of the sources, we're exploring and are dop dive
- 2:08today the stakes because completely astronomical.
- 2:13The special constrance or really what turn this from a simple
- 2:15landscaping is you in to a full blone high sticks engineering
- 2:19crises because. It's not happening in the mittel
- 2:21of nowware. Right the operations detailed
- 2:24the material takeplace in the rinland specifically are on the
- 2:27clone and bone regian in Germany, so you're likeing at an
- 2:30investment, we're this massive histor trees or titly wetch
- 2:35between modern hospitals for an embasies.
- 2:38Incredible expensive realistate. And just every they petestrian
- 2:41infrastructure, you're a walking around.
- 2:43Exackly and uncontrolled fall of that much what biomass and such
- 2:47a constrange urban sener it trugers a castgate of
- 2:50destruction, the impact creatoring alone from that we
- 2:53can rubsure underground gasmans. Well, just from the shure force
- 2:57of hiting the grand just. The impact ja, it's shaders
- 3:00underground fibor optic Networks.
- 3:03And it can completely carpromise the struxful foundations of any
- 3:06a js and historical phasards. So basically the traditional
- 3:09lumber Jack approachine a guy and applesure just swinging in
- 3:13ax and jeling timber in two and MT for as that is totally
- 3:17absolute here. Oh compleity connope a lot to
- 3:21dictate Evan a single fraction of a second of the trees to end.
- 3:24Because there's no room for error every square sonometer of
- 3:28the drobzone has to be calculate and completely controlled.
- 3:31We's in Assassitate, so the Plint.
- 3:33Mit of higly specialies climers they operate under what is known
- 3:36is the English double rope Technik.
- 3:38Ja, i want to the ask about this because one i review the visual
- 3:42data on this teams from are sources.
- 3:44They operate muchmore like i don't know and a lead alpine
- 3:48mountain rescue unit them traditional foresters.
- 3:50That's the grate comparison actually the geometry of urban
- 3:53arboro culture requires accessing the absolut
- 3:56extremities of the kind of be, but it out and do'sing a
- 3:58katastrophe wetransfer. Because if you shift your wate
- 4:01rong, you can't collapse the we're structure your trend to
- 4:04dismantal they's like it's hoveralians on such at complex
- 4:09dynamic rope system really puzzle me because you know if
- 4:13you have a that or. Sevirly compromise Tree don't
- 4:17arbor is some times just used. There's have you metal spikes on
- 4:20there boots to scale the trunk. They do just for ramuval
- 4:24somtime. Right what I'm they just clime
- 4:26up using metal spikes on there boots and drop the son of pieces
- 4:30down that's them so muchies your them all these robes.
- 4:33We'll first off throwing pieces down what absoly smash the
- 4:36grandal that infistructure we just takt about but more portly
- 4:40if the tree is being reserved or even just prund.
- 4:43They'll Spike surstricly Forbidden.
- 4:45What just because it herts the bark?
- 4:48It's way was the that right, you're a vective the punching
- 4:50hunders of deep chromatic puncheroons directory three the
- 4:54bark and in the vasqual octicio with the tree, the sellular
- 4:57damage from climin spikes is just devestating.
- 5:00And I'm realies one that deep. You're repeatedly piercing the
- 5:04flom and the cambium lare it complatey bipass is the trees
- 5:09external defenses and interdus is a direkt vector for.
- 5:13Aggressivly pathagonic funji in Backteria.
- 5:16So it's basically like if a sergeant operate on you with
- 5:20rusty unsteralize tools. That's start on, we'll a treek
- 5:25in a temp to compart memalize that the k you're for think it
- 5:28to expand critical energy to seal hundreds of puncture roons
- 5:31well it's already under invirendal stress, it is
- 5:34biological savatosh. Ok, so the English obal rob
- 5:37System comply alliminates that mechanical damage.
- 5:40Intirally. Because they are it's likeing in
- 5:43to the trunk it fundamentaly changes the climers relationship
- 5:46the gravity. On like Rock, climer is who
- 5:48continuity secure them souls to the vertical phase is the asan
- 5:51right. This arbor is the shoed a line
- 5:53hi in to the strongest and the central point of the intec crown
- 5:57to said a primary anker. They are sensually suspending
- 6:00them souls from the sealing of the.
- 6:01Organizum that's wild so they's going to.
- 6:04A hanges and what two a justible lions roning back down to there
- 6:07harness the. A chief full three dimensional
- 6:11Mobility to the intire Crown space.
- 6:13So that dynamic suspension is the corr genius of the technic.
- 6:17It really is the climer central of gravity is from the lim,
- 6:20they're physically touching the tention in the harness and you
- 6:25know the friction nots on the dual lines distribute they're
- 6:28mass upbured to that central anker.
- 6:30What means they are pudding all they're on the branch they's
- 6:32standing. On it's like they's a lot of the
- 6:34climer to trevers litory literity walking out to the very
- 6:38tipps. Of Incredible fragel Hors on
- 6:41will branches that madmaticly good never support a human
- 6:44static wate. Well it a lousened position
- 6:47them's like a spider in a web, just a spended twenty meters in
- 6:51the air with a warring chance out's like a batanical swat
- 6:54team. It's an tens environment up
- 6:55there. But this that's up a terrifine
- 6:57physics problem is that what's AA climer suspended on there a
- 7:01justable lions needs to a damage lateral branch.
- 7:05A peace of satriated hard with what's they three Meter is long
- 7:08wing raffly five hundred kilograms a.
- 7:10Very comensnarial. One the chainsaw sebers that
- 7:14have ton of what wood the kinetic energy has to go some
- 7:17more. I'm in if it falles it
- 7:18anniolates the consturbatory baloe, but if you tride a hold
- 7:22it, the sodn chocolate will violent me rip the climer right
- 7:25out of the tree or catopoled the grand work or holding the
- 7:28stratistial like a bad cartoon. This is where arbora culture
- 7:32transitions in to pure h stak. Structural engineering the
- 7:37process is call to rigging long. Bevor the sos t even touch the
- 7:41bark, the structural lot of the five unter Kilo branch is
- 7:45transfer to a completely independant, have you do the
- 7:48rigging system? So the Climer us and bear the
- 7:50late. At all not even in ans of it,
- 7:52the climer installs a specialized polly call to
- 7:55rigging blog at a carefully calculate structural vertex.
- 7:58Some more about the cut so. Detail a hitans iload roped to
- 8:02the branch one of two the blog and some the tail all the way
- 8:06down of the Gran. But the gran we're going on
- 8:08human biomican x to manage i have ton of free falling
- 8:11timberate there's no way a person can just musel that.
- 8:15No absolut in out that be crushed or lunched the youlize a
- 8:19massive solid steeloring sound or strap to the base of the
- 8:22trunk. We just not us a bolert.
- 8:24And this is where the thermal dynamics of the operation becom
- 8:27genualy fasinating i was reading this part.
- 8:30My mind is blon. It is all of about friction and
- 8:32he disopation. Yes, what's fastnating here is
- 8:36have the boward x as a master class in applite physics.
- 8:41The grauen worker takes to disending lowed rop and rap sit
- 8:44around that solid steel, drum a specific number times.
- 8:47Ok so one the climer's severs the Branch, the 500 Kilo Mass
- 8:51Plumets. And the rope violently Snaps
- 8:54tot, but Institute transfering that a men's shock wave to a
- 8:57human spine or backup in to the fragal operacanity.
- 9:00With what the story, the tri? The kinetic energy at the
- 9:03falling wo it is rapidly converdid in the firma energy.
- 9:06The friction of the synthetic rope hissing around it's deal
- 9:09silender upsorb's the violent forses.
- 9:11The mental rismatic required by the grandwarker in no slate
- 9:15three seconds for for the cut is stagring they're likeing twenty
- 9:19meeters up in to the canopy trine to assested dancity of the
- 9:22what because. I me in Assatriated Peace of Oak
- 9:25Behaves intirity Differenty on the Gravity, then a dry ps of
- 9:28Pine. Oh not they differents they have
- 9:30to. Calpulate the executory and
- 9:32crusally the drop distance bevor the rigging rope in gages
- 9:36because. Kinetic Energy incruses
- 9:38exponentialy with the distance of freefall the shock lot.
- 9:42A Five hundred keylows droping one meter is westly vestly
- 9:46different from that same us droping three meters.
- 9:49So, the grandwicker must factor all that in.
- 9:51Everything dealasticity of the syndetic rope the specific
- 9:55moisture content of the wood. The thermal coefficient of the
- 9:58bard they have to calculate all that instantly to to german
- 10:01exackly hammy raps of the rope to place on the steal center.
- 10:05And the margin for error is actible zero.
- 10:08Because if the grown worker underestimates the mass right
- 10:12and applice one rap to few the fiction call afficient is
- 10:16insufficient the rope surgestor the ballert melting the
- 10:20synthetic fibers from the heat. And the lot is completely last
- 10:24have a ton of word just excelerate street two the glass
- 10:27roof blow. On beliefable, but what I've
- 10:29going to the ray, what of the ply one rap to many.
- 10:31That's are you really was for the climer?
- 10:34If there's to what striction it loxed the rope that on the the
- 10:36steel when the massive branch drops and hit the end of a lox
- 10:40system, the dynamic energy as no word a disopate.
- 10:43Can't sly to brunoff the energy. Right, so the resulting shock,
- 10:47wave travels, instantaniesly backup the rope hits, the
- 10:50rigging Block and can generate in of lokalized forest to snap
- 10:53the top of the tree clinoff. Take in the climers primary
- 10:56incrapoint right. With it, it's a hilly leath on
- 10:59the stak. It's basic it high consequence
- 11:02belly of hevy machineering. Ravity when the cauculus is
- 11:06perfekt, the Ballard absorbes the extreme forces, the rope
- 11:09wines against the hot steel and the grand worker just smudely
- 11:13lowers the multi tontimbur past the fraggal macering with like
- 11:16millimeter procision. It really is an incredible
- 11:19application of physics on a living organizum.
- 11:22But you know vuing this incredible spectical really
- 11:25reframes the ultimate goal of this a le r borgalter teams.
- 11:29Because taking the treedown no met or how spectacular of the
- 11:32ropework is is fundamentaly in den Mission affilia.
- 11:35Xacly true arbora culture is about reservation felling or
- 11:40dismantling is the absolute last resort and structure integrity
- 11:44as completely unrecovery failed. Right they one a save the tree
- 11:47not chopin in the firelit. The farmore critical new ons
- 11:50aspekt of there profession actually relies on microbiology
- 11:54and advance potanical diagnostics.
- 11:56The primary objective of the company is to the tech and
- 11:59medigate invisible hazards long bevor the structure matrix of
- 12:02the tree de grates to the point of requiring that crazy hitans
- 12:06out rigging. This diagnostic Prozess is
- 12:08remarkable the certify tree inspektors employed by this
- 12:12companies. They don't start by digging of
- 12:14the red system they used the foliage in the summar canopy as
- 12:18a highly sensitive systemic reed out.
- 12:21Just belies. It axs essential as a biologgal
- 12:24mri ray you look up at the Leafs and they broadcast the exact
- 12:28nature of the microscopic fillers, a curing deep baned the
- 12:31soil that. Diagnostic acreci of the foliage
- 12:34is tidor reckly to the hydrolic pipline we discestralier.
- 12:38The tree is continuity drying hundreds of leaders water have a
- 12:41leading with this all of minerals from the micro scopic
- 12:44rutiers up to the vasquer or tissue of the trunk and out of
- 12:48this tomot of the Leafs. For photo sympathes they like
- 12:50tiny highly efficient solar panels.
- 12:52Exackly and because the folie is the terminal endpoint of this
- 12:55mass of ploming system. Any microscopic interruption on
- 12:59the pathway instantly manufest visualy in the canopy.
- 13:02So what i's have a notes in are sourses on cloroses with just
- 13:05that pale yellowish bleaching appearing between the green
- 13:08vains of the lears or just unusually small ears.
- 13:11My First Instinct was simply will nutri and por soil.
- 13:16I as my Soft conpail Leafs just mean the soil and that's but is
- 13:19naturally pore. I asumed to just need it some
- 13:22chemical fertilization. That's what most home one of the
- 13:25soom, but the meckanism driving this in urban enviramance is
- 13:28really a like of anby and nutrians it's farm or complex
- 13:32off and it's a structural suffication of the rus system.
- 13:35Suffication like they literally can't brief.
- 13:37Yes, so a compaction is one of the silent and liefal urban
- 13:41stressers. When have a delivery trucks park
- 13:43on the grassfurge or construction machineery uprays
- 13:46new or the rootzone the sher mechanical wate compresses the
- 13:49soilestrucks. Oh i See.
- 13:51It for as is of the microscapic air and water pockets that are
- 13:54appsal the essential for the survival of the fined absorbing
- 13:57roots. So if you've resently have say
- 13:59contractors park the vans on your landering a home
- 14:02ronnevation you're kind of unnowingly initiated this exect
- 14:06sufficate and process. The bolk dancity of the soil
- 14:09incruses to basically a bricklate consistancey.
- 14:13Right and the rutes literity can not performance souial a
- 14:15resperation there is fixiate and die the i'm up take seasis
- 14:19intirity and twenty meeters above the leves loser
- 14:23chlorophill intern paleal. That is tragic on asly just from
- 14:27a parked van it. Happens all the time
- 14:29alternatively that sain cloroses can't indicate a path of genic
- 14:33invasion of the vasco or to. You can you do.
- 14:35See the rutes my be perficly functional and good soil, but in
- 14:39aggressive fungal investition as penetrator designum.
- 14:42Physically Clogging the Vascular pathways and black in the
- 14:45caplarry action required to pole water upord.
- 14:47So the diagnostic capability to Reed, There's sodal
- 14:50leaferiations all also the arboristed in a vinary, maybe
- 14:53was soilariation or targid it fungal tripment.
- 14:56As is all of a proventive care. But the diagnostic toolkit
- 14:59extens be on just reading the foliage the Integration of lokal
- 15:03wild live in to the diagnostic protocal as fastinating.
- 15:07This inspecters activity of the acustic behavior of whitpackers
- 15:11to locate internal. The k that is intarially
- 15:14invisible from the outside. The fatherinspecters yeah
- 15:18whatpackers because as and extraordinary acustic
- 15:20sensitivity to the resident frequencies of what they're not
- 15:24just drilling randomly hopeen of find a book.
- 15:26Grilly they know it's like, we're a go.
- 15:28A absolute they're i soliding the acustic signatur of specific
- 15:32with borning insect companies. In the specific insex required,
- 15:37a viry particular micro environment to frive nämlich
- 15:40what that is ardibing companies, but funkle the k and is actually
- 15:44undergone leged in break down. Ok, so the bark on the outside
- 15:47of the trunk mightlet perfical robust and solid human i's
- 15:50completely masking. The internal structural failure,
- 15:53but when the insector's a whitpacker in tensly working on
- 15:56one specolated quadron of the trunk, it is a definitive
- 16:01biological indicator, it's. The Bird is acting as.
- 16:04Like Hilly persise acoustic scanner, it confirms that deep
- 16:09with in the hard with there's an the krotic dekan kvedy even of
- 16:13the barkis pristin. And i don't find that hit in
- 16:15kvedy really allows for proventive structural proning by
- 16:20carefully redusing the wate on the company section of the
- 16:22canopy, the arborest can rebalance the lot.
- 16:26Exackly you're provent a catastrophic sure filly are in
- 16:29the extlinstorm saving the tree and you know awarding the dram
- 16:33of the five on the kul of. Like branchentiry.
- 16:36Speaking of hidden to k this brings us to a biological thread
- 16:39that can't really can't me of guard it canpliy shift it my
- 16:42perspektive on guard and mainance.
- 16:44We have to examin the underground battlefield
- 16:46triggered by something as mondayen as a left of a
- 16:49treestump. Oh the stumps.
- 16:51Yeah, here's we're it's really interesting and a little
- 16:53terrafing if you have a fell, the sictory and left the ragids
- 16:57stump sitting in your front gardin out of sure convenience a
- 17:00suming was just a peski tripinghaser or and is or the
- 17:03steer the launmore around you have in it virtually cultivate a
- 17:07pathed johnnic beached. People think a stump is just a
- 17:09that pes. What?
- 17:11The concept of a garden is a collection of isolateed banine
- 17:15plants is a massive miss conception but need the soil it
- 17:19is a dansly interwolven hily competitive and rutles eco
- 17:22system. It's Biological Warfare Down.
- 17:24They're trally we you it're do's a massive concentrated supply of
- 17:28that carbon and soulos in the that environment in the form of
- 17:31a stump nature respons aggressivly a that's stump is
- 17:35assentally and all you can't buffay for what the kang fun
- 17:38Guy. It is in just passive d
- 17:40composition. No it is the invitation of apex
- 17:43botanical predators, the primary thrat highlight it in r sources
- 17:47is the notorious honeyfunkes or armelaria.
- 17:50And this organizum this and just passively break down that we're

- 18:03It is the stump as a base of operation.
- 18:05Exackly the Stump ex is an energy is of war a loting the
